HAMM DV PLUS 70I VV-S STATIC SMOOTH DRUM ROLLER

Technical Description

The HAMM DV PLUS 70i VV-S is a high-performance smooth drum roller designed for efficient compaction in road construction and civil engineering projects. It features a robust Kubota V3307-CR-T diesel engine delivering 99.7 hp (74 kW) at 2200 rpm, meeting EPA Tier 4 emissions standards. The machine has an operating weight of 23,060 lbs, with a ground clearance of 24.1 inches and a height to the top of the cab at 9.8 feet, ensuring optimal stability and visibility on site. The roller is equipped with dual smooth, split drums each 59.1 inches wide and 44.9 inches in diameter, with 0.7-inch thickness, producing centrifugal forces of up to 15,287 lbs on high amplitude and 15,062 lbs on low amplitude settings. Vibratory frequencies are adjustable between 42 and 50 vibrations per minute, with nominal amplitude fixed at 0.1 inch, enabling precise compaction control. The machine offers a static linear load of 149.6 pounds per inch of drum width, complemented by a 4-degree oscillating angle to improve contact with uneven surfaces. It operates at a maximum working speed of 6.9 mph (10 kph) and incorporates a water spray system with a 208.2-gallon fluid capacity to prevent asphalt sticking. The roller's dimensions include a 163-inch overall length, 5.6-foot overall width, and a tight 9.2-foot inside turning radius supported by a 118.2-inch wheelbase, contributing to maneuverability in confined spaces. Fuel capacity is 39.1 gallons, supporting extended operation in the field. This combination of power, precision, and durability makes the DV PLUS 70i VV-S suitable for a wide range of asphalt compaction applications.
